Most interesting is that md devices (major == 9) with
minor numbers of 512 or more will no longer be created
simply by opening a block device file. They can only
be created by writing to
/sys/module/md_mod/parameters/new_array
The 'auto-create-on-open' semantic is cumbersome and we
need to start moving away from it.
